A small framwork for the custom presentation of view controllers
- Swift 4
Add this line to your Cartfile:
github "Chandlerdea/ViewControllerPresentation"
You can just drop ViewControllerPresentation.xcodeproj into your project and then add ViewControllerPresentation.framework to your app’s embedded frameworks
This framework uses the default animation for presenting view controllers, but uses the view controller's preferredContentSize to display the presented view controller. Here's what the default animation looks like:
There are two animations that you get out of the box: default and overlay.
The default animation is modal, from bottom to top. The presented view controller will be pinned to the bottom of the presenting view controller. See the gif above for an example
ViewControllerOverlayPlacement defines 3 different positions: top, center, and bottom. Both top and bottom have an associated value, which is used for padding. To use this animation, you use a ViewControllerOverlayTransitionAnimationController, which takes a ViewControllerOverlayPlacement in the initializer.
Using the framework is very easy.
let vc: UIViewController = .....
vc.modalPresentationStyle = .custom
vc.transitioningDelegate = self.animationController // We need a strong reference to this property
self.present(vc, animated: true, completion: nil)And that's it!
I have application tests for the default and overlay animations. The application tests are like unit tests, execept you have access to view controllers, and objects in your application while it is running on the simulator. This is ideal for testing view controllers.
If you find any bugs, or have any critiques, please open a PR and I will fix them as soon as I can. And if you feel the need to add some more tests, you're more than welcome!
